[dpdk-dev] [PATCH v3 2/2] net/ice: merge inner/outer flow seg info for FDIR

[Zhirun Yan]

For tunnel and non-tunnel packets, it can share the same seg_tun info.
seg_tun[1] can be used for supporting inner fields with tunnel flow rule
or for non-tunnel packets, seg_tun[0] only used for tunnel outer part.
Add outer_input_set to distinguish inner/outer input set. So we can
identify different fields in outer or inner part.
